Abstract (en)

[origin: CA2232556A1] The invention concerns a control device for a diesel-operated internal combustion engine, said device comprising a mixer unit (5) in which diesel and air can be mixed to form a fuel mixture, a diesel feed line (2) which feeds diesel to the mixer unit (5), an air feed line (3) which feeds air to the mixer unit (5), a fuel mixture line (4) which feeds the fuel mixture out of the mixer unit (5) and into the internal combustion engine, and an adjusting device (6) which adjusts the flow of diesel through the diesel feed line (2). In order to provide for a diesel-operated internal combustion engine a control device which reduces the fuel consumption and pollutant emissions by optimizing the combustion process, the control device according to the invention further comprises a heater (7) which dehumidifies the air flowing through the air feed line (3) and heats this air to a uniform temperature, a control unit (8) which is disposed in the air feed line (3) downstream of the heater (7) and controls the flow of air through the air feed line (3) as a function of the engine speed, and a limiter unit (12) which is disposed in the air feed line (3) downstream of the control unit (8) and predetermines the maximum amount of air which can flow through the air feed line (3) into the mixer unit (5).
